Hello Sruthi Your onSubmit() method does not expect any arguments. But from your html you call it with one argument: onSubmit(serviceForm.value) I would remove the parameter from html just simply use onSubmit() Thanks

You can improve the accpeted answer by doing the following: Use type annotations to make your code more readable and maintainable. You can specify the types of the function arguments and the return value. onFormSubmit(value: {EmpName: string}): void { // sample to get value of form const empName = value.EmpName; } Another improvement is use destructuring to extract values from objects and arrays and assign them to variables. You can use destructuring to extract the EmpName property from the value object. onFormSubmit({EmpName}: {EmpName: string}): void { // sample to get value of form const empName = EmpName; }
